Headlamp Control Module (HCM) (China only)
WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
The Headlamp Control Module (HCM) uses inputs such as suspension height and vehicle speed from the VDM and PCM in order to determine vertical height of the headlamp beams and adjusts actuators in the headlamp assemblies as needed.
